COMBINATION CHAIR AND BED.

Specification of Letters Patent. Patented Mar. 18, 1919.

Application filed October 18, 1917. Serial No. 197,302.

To all whom it may concern:

Be it known that I, EDWARD HANSEN, a citizen of Sweden, residing atSeattle, in the county of King and State of Washington, have inventedcertain new and useful Improvements in Combination Chairs and Beds, ofwhich the following is a specification.

This invention relates to improvements in combination chair and bed andhas for its principal object to provide an improved and novel type ofchair which may be folded in such a way as to form a cot or bed; toprovide in a combination bed and cot, novel spring means for assistingin normally returning the device to the chair position. Another objectof my device is to provide simple and cheap means of constructing achilds chair whlch is easily converted into a cot.

Other objects will appear as my invention is more fully explained in thefollowing specification, illustrated in the accompanying drawing andpointed out in the appended claim.

In the drawings, Figure 1 is a perspective view of my device shown as acot or bed. Fig. 2 is a side elevation of the device shown as a chairwith parts broken away. Fig. 3 is a fragmentary front elevation of theoperating mechanism of the device.

Referring more particularly to the drawings, numeral 1 indicates sideframes having legs 2 and upstanding side arms 3. The side frame, legsand arms are arranged in parallel pairs and are held in spacedrelationship by means of a chair bottom 4: and leg braces 5. To one endof the chair bottom 4:, a back 6 is hinged as at 7 and is provided withside members 8 which are cut away as at 9 to leave space for the end ofthe side arms 8 to project past the shoulder of the side members 8. Ahead rest 10is secured to the front end of the back 6. It will be notedthat side members 8 extend outwardly beyond the back 6 and that a falseback 11 is hinged as at 12 intermediate the side members 8 and outsideof the back 6. The false back is dropped down and used as a leg when thedevice is in the cot position as shown in Fig. 1 and folds in againstthe back 6 when in the chair posltion as shown in Fig. 2. At theopposite end of the chair bottom 1, a foot extension 18 is hinged as at14. Foot extension 13 is provided with tapered side boards 15 which whenin the chair position rest against the front legs 2 in order to hold thefoot member at the proper angle. When in the cot position, the footextension member 13 is held in the same plane as the chair bottom 4. Afoot rest 16 is secured at right angles to the member 13 and is utilizedto support the foot when in the chair position and as a foot board whenin the cot position. It will be understood that the outside width of theside frames of the chair are the same as the outside widths of the footextension member and of the back so that the device when in eitherposition presents a continuous side line. The operating mechanism forconverting the device from a chair to a cot or vice versa, includes aback lever 17 which is secured to the back 6 and which extends well downbelow the back and nearly to the members 5 when in the chair position. Alink 18 is secured at one end to the lower end of back lever 17 by meansof a spring hinge 19 and is pivoted at the front end to a rod 20 whichpasses through side boards 15. It will thus be seen that the backportion and the foot rest portion of the device are connected by linkand lever means. Tension rod 21 passes through link 18 adjacent springhinge 19 and is slidably retained at its ends in slotted quadrants 22,one on the outside of each side frame 1. Thumb nut 23 serves to tightenup or set the tension rod 21 in order to retain the lever 18 in anydesired position of its travel. It'will be understood that the slots inquadrants 22 are arranged in such a way that'as the back is thrown downabout the hinge point 7 and the lever 17 and link 18 straighten out thetension rod 21 will travel freely in the slots. The spring 19 tends todraw the lever 17 and link 18 into. position shown in Fig. 2 and therebymaterially assists in returning the device from cot position to chairposition. A childs high chair table 24 may be slidably used upon tops ofarms 3 when the device is in chair position. This table is remov able.

While I have shown a particular form of embodiment of my invention, I amaware that many minor changes therein will readily suggest themselves toothers skilled in the art without departing from the spirit and scope ofthe invention and I therefore desire to avoid being limited to the exactbination of a central chair section including legs, a bottom andvertical side members extending up from the bottom, the rear edges ofthe side members inclining upwardly and outwardly, a back section hingedto the bot- .tom, the sides of the back section being cut away to formoverhanging flanges, the cutaway portions engaging the upwardly inclinededges of the vside members and the flanges engaging over the top edgesof said members, ,a bar depending from the back section, a foot resthinged at its upper end to the front of the bottom, a link pivoted atone end to the ioet rest, spring hinge connecting the opposite end ofthe link and the lower end of the bar, a pair of curved slotted guideson the sides ofthe central chair section, a rod extending through theslotted guides and the link, lock nuts for clamping the rod to theguides, and folding legs pivoted near the upper portion of the "back,whereby when the back is thrown down the link connection will elevatethe foot rest and a bed will be formed, the back being supported by the"legs.
